HYDROCARBON-BURNER.

SPECIFICATION forming part of Letters Patent No. 69 3,682, dated February 18, 1902. Application filed April 2'7, 1901. Serial No. 57,763. (No model.)

To M6 whom it may concern:

Be it known that we, JOHN M. BEECH and LUKE P. BEECH, citizens of the United States of America, and residents of Norwood, in the county of Hamilton and State of Ohio, have invented certain new and useful Improvements in Hydrocarbon-Burners, of which the following is a specification.

This invention relates to certain improvements in hydrocarbon-burners such as are especially adapted for use in burning liquid fuel; and the object of the invention is to provide a burner of this general character, of a simple and inexpensive nature and of a light and durable construction, adapted for burning heavy oils, such as crude petroleum.

The invention consists in certain novel features of the construction, combination, and arrangement of the several parts of the improved hydrocarbon-burner, whereby certain important advantages are attained and the device is made simpler, cheaper, and otherwise better adapted and more convenient for use, all as will be hereinafter fully set forth.

The novel features of the invention will be carefully defined in the claims.

In the accompanying drawings,which serve to illustrate our invention, Figure 1 is a perspective view showingastove havingaburner constructed according to our invention applied thereto. Fig. 2 is a fragmentary side elevation showing the arrangement of the feed and overflow pipes and the controllingvalves outside of the stove. Fig. 3 is an enlarged partial section showing one of the bu rners in axial vertical section. Fig. 1 is a section taken transversely through the burner in the plane of the line a a in Fig. 3.

In the views, 1 indicates the stove to which our improved burner is applied. This, as herein shown, is an ordinary cooking-stove; but it is evident the improved burner may be applied as well to other stoves and to furnaces, ranges, and heaters generally. At the back of the stove is supported a tank 2 for containing the liquid fuel, and from said tank a pipe 3 is extended along one side of the stove to near the front part thereof.

The forward end of the pipe 3 is bent downward, as shown in Fig. 1, and is connected by a suitable coupling at with two pipes 5 5, extended up outside the stove and parallel with each other and having their upper ends connected to the arms 6 6 of a U-shaped coupling member 7. With said arms (5 6 of the member 7 are also connected feed-pipes 8 8, which are extended horizontally or at right angles to the plane in which the pipes 3, 5, and 5 extend and are passed through openings in the side of the stove, as shown in Fig. 3. Valves 9 9, carried by the arms 6 6 of the member 7, are arranged to control the flow of liquid fuel from the pipes 5 5 into the feed-pipes 8 S,and said valves have indices 10 10, playing over scales provided with stops 11 11, by means of which the movements of the valves are controlled, so that too much liquid may not pass the valves.

There are two burners herein shown applied to the stove 1, although but one or any desired number may be employed. Each of these burners comprises a circular cup or receptaele 12,having meansfor connection with one of the feed-pipes S 8 at its lower part, so that the liquid fuel from said pipe is discharged into the hollow of the cup'or receptacle 12 through an opening centrally formed in the bottom thereof. In the cup or receptacle is held an absorbent packing 13, of asbestos, to permit the liquid fuel when discharged from the feed-pipe into the cup or receptacle to be more readily ignited. Above the cup or receptacle 12 is extended a funuel-shaped draft-tube 14:, formed, by preference, from soft sheet-copper bent into shape and riveted, as shown at 15. The draft-tube 14 has at its contracted upper end an annular projecting flange or lip 16, which is supported above a sheet-metal plate 18, extended across the fire-box of the stove 1, the parts being so arranged that the flames from the fuel supplied to the cups or receptacles 12 are carried by the draft up through the draft-tubes 14 and are permitted to spread and expand in the upper part of the fire-box of the stove above the sheet-metal plate 18, so as to thoroughly heat the stove.

The plate 18 has an opening 17, through which the flanged upper end 16 of the drafttube 14: is adapted to be passed, and to secure the draft-tube in place in said opening we provide for each of the draft-tubes a slide 19, arranged to move along guides 20 on the plate 18 and arranged to take under one side of the lip or flange 16 of the draft-tube, the other side of said lip or flange resting on the upper face of the sheet-metal plate, as shown in Fig. 0.

The larger lower end of the draft-tube 14 is extended slightly within the cup or receptacle 12 and is of less diameter than the outer Wall of said cup, so that an annular airopening 21 is provided for the entry of air to support combustion of the fuel in the cup or receptacle. The interior of the draft-tube affords a tapering flue 22, through which the gases from the burning fuel are carried up into the fire-box of the stove.

The central part of the U-shaped couplingmember 7 has connection outside of the stove with an overflow-pipe 23, which is carried down and extended toward the rear of the stove and is adapted to discharge into a tank 24 at the back of the stove and below the tank 2. The tank 24 will be, by preference, removable, so that its contepts may be poured when desired into the fuel-tank 2. The connection of the overflow-pipe 23 with the member 7 is in line with the desired level of the liquid fuel in the cups or receptacles 12 and serves to prevent the cups from being run over in case too much oil be supplied to them or if thefire be extinguished from any cause while the valves are opened.

In operation the cocks or valves 9 9 are manipulated to supply fuel through the feedpipes 8 8 to the cups 12, and the fuel in said cups is then lighted, air entering for combustion of the fuel through the annular air-opening 21, and the flames passing up under the draft through the flues 22, formed by the draft-tubes 14, into the upper part of the firebox of the stove, where they are permitted to expand or spread and heat the stove. In this way the oil is completely burned and little or no residuum is left in the cups or receptacles 12, so that the burner is especially well adapted for burning crude petroleum, there being no carbonizing or waste of the fuel. The draft-tubes ll also, being formed from soft copper, are adapted to retain sufficient heat to maintain them at redness, and thus prevent the deposition of carbon in the form of soot in the flues 22, so that the flues are prevented from becoming clogged and choked up, and the device is thus adapted for continuous use and requires no cleaning for the removal of soot.

The improved burner constructed according to our invention is of an extremely simple and inexpensive nature and is especially Well adapted for use in burning fuel-oils, since it permits of perfect control of the heat by manipulation of the valves 9 9, and also avoids odors from the fuel, all of the gases being drawn by the draft up through the draft-tubes and into the fire-box of the stove, whence they are conducted to the chimney.

The device is also capable of being readily applied to stoves and heaters of all kinds and is not liable to become deranged or broken when in use. It will also be evident from the above description -that the improved burner is capable of some modification without material departure from the principles and spiritof the invention, and for this reason we do not wish to be understood as limiting ourselves to the precise form and arrangement of the several parts of the device as herein set forth.

Having thus described our invention, we claim 1. A burner comprising a cup or receptacle for containing fuel-oil, said cup having raised edge walls and having means for supplying liquid fuel to it, a draft-tube extended above the cup or receptacle and having a central draft-flue, said draft-tube having its lower end arranged within the cup or receptacle but spaced away from the edge walls thereof to provide an opening for the entry of air for the combustion of the fuel within the cup or receptacle, and means for maintaining the fuel within the cup or receptacle at a level below the lower edge of the draft-tube, substantially as set forth.

2. A burner comprising a cup or receptacle for liquid fuel having raised edge walls and provided with means for supplying fuel to it, a draft-tube extended above the cup or receptacle and having a central draft-flue, and having its lower end arranged within the cup or receptacle but spaced away from the edge walls thereof to provide an opening for the entry of air for the combustion of the fuel within the cup or receptacle, said draft-tube being formed from a sheet of soft copper rolled into conical form and having its edges lapped one over the other and rivets passed through said lapped edges, substantially as set forth.

The combination of a heater having a fire-box, a plate extended across the fire-box and formed with an opening, a draft-tube having a contracted upperend passed through the opening in the plate and formed with a flange one side'of which rests upon the plate at one edge of the opening, a slide on the plate and on which the other side of said flange is rested, a cup or receptacle having raised edge walls within which the lower end of the draft-tube is held, and means for supplying liquid fuel to said cup or receptacle, substantially as set forth.

4. The combination of a cup or receptacle having a fuel-opening in its bottom, a drafttube extended above the cup or receptacle, fuel-supply pipe connected to the lower part of the cup or receptacle and connected to a fuel-tank, a valve controlling the fuel-supply pipe, a member having connection with and extended above the fuel-supply pipe and an overflow-pipe connected with said member in line with the fuel-level in the cup or receptacle, substantially as set forth.
